Engine/Transmission (1998.5 - 2002) What are the guesses on this problem

[Batphreak]

Started just a couple days ago. Very erratic every once in a great while between about 45 and 55 I get the torque converter lock/un-lock problem. Seems to do it twice, then decides to stay in lockup. Then Monday afternoon, temp well over 90 DegF, truck starts slowing down from about 60, I push the pedal for more, dead, nothing until I get it to downshift, then after hesitating it adds fuel and takes off. No CEL on, I checked codes with the Superships programmer (it came with the truck, I have never had it reprogram the truck, my transmission is only 10K old, still under warranty) all I had is a P1693 (fault in a companion module). No other DTCs. When I got the truck in January there was a laundry list done to it. transmission replaced with re-man, LP replaced with in-tank (old one wasn't bad, just growling, figgered while it's getting the transmission done might as well replace), exhaust manifold, few other small things.



Don't have a FP gauge, I'm a little scared what it may show. Because of the 2 dif. symptoms I'm hoping its the Bell-crank (throttle position). Guess I'll start saving for a VP just in case. Any other ideas?

There are two things that come to mind, the electrical noise problem and the APPS reset. Hers are links to some info on bothe. bg https://www.turbodieselregister.com/forums/showthread.php?t=146239 https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=65677

Well, I haven't tried the APPS reset yet. The problem hasn't shown up for almost 2 weeks. Then on Friday I'm heading home, I got the T/C unlock once, and had dead pedal quite a few times. Couple things I've noticed on this, both times I've gotten dead pedal I've had less that 1/8 of a tank, and it's been pretty hot 90Deg+. I'm starting to wonder if the thing is sucking air with a low tank. If the T/C problem happens again I'll try the reset. It hasn't thrown a CEL yet, I have checked the codes, only one is still the P1693. Is a Dodge reader the only way to see a possible P0216? Can anyone tell me if a P0216 will always set a CEL?
